PROJEGTILE SHOOTING GUN Filed Aug. 21, 1931 nveniqr `/qllomey PatentedAug. 23, 1932 UNITED STATES PHILIP C. TRAVER, OF I'YVNBROOK, NEW YORKPROJECTILE SHOOTING GUN Application filed August 2.1, 1931. Serial No'.l558,606.

This invention relates to a unique type of toy for shooting projectiles,the structure being such as to justify the adoption of the title gun.

As the latter term implies, my idea is to provide a different andunusual type of gun of a simple and economical and efficient type usingair pressure for forcibly dejecting the projectiles flight.

Briefly stated, this improved pneumatic gun is characterized by a drumhaving a drum like sound producing and developing device and a balldirecting barrel, together with means for pregressively feeding balls orprojectiles into the barrel for successive projection.

In the drawing: Figure 1 is a plan view of a structure developed inaccordance with the present in- VelilllOn.

Figure 2 is a side View of Figure 1. Figure 3 is a section on the line3-3 of Figure 1.

The numeral 4 designates the pressure developing or pneumatic impactdevice. This preferably comprises a pan-like receptacle having aconcavo-conveX bottom 5 and an upstanding annular rim 6 provided with achannel shaped bear 7 constituting a retaining clamp for the peripheraledge of a flexible drum slrin diaphragm 8. Connected with the rim at apredetermined point is a T- shaped coupling 9 containing an internalshoulder forming nipple 10. Secured to the longitudinal branch of thiscoupling is a tube 11 which functions as the barrel to deliver theprojectile balls. Incidentally I find it exceedingly practical to uselight weight celluloid hollow balls of the type used in games a0 of theping-pong type. The balls can be inserted one by one by hand forshooting purposes. It is desired however to provide a continuousshooting gun for which reason I find it better to provide a deliverymagazine 5 which comprises an upstanding cylinder 13 constituting acontainer for the superposed balls. On the upper end of this cylinderthere is a removable closing cap V14 having slot 15 coopera-ble with theretaining pin 16. In the upper portion of the magazine cylinder a coiledexpansion spring 17 bearing on a" follower disk 18 presses down on theballs' to deliver them successively into the barrel to occupy vthedesired shooting position. The numeral 19 in Figure 3 designates ballretain- 55 ing spring for holding the balls temporarily in place beforepreparing for projection.v The balls are prevented from being suckedinto the drum casing by the nipple 10 which functions as a stop orshoulder.

. The desired concussion of air is developed by hitting the fist of palmof the hand thoroughly on the iiexible lskin diaphragm 8. This providesthe impact noise amplified by the pan 4L. In fact the pan servessomewhat 65 as a resinator producing the desired quality of noise. Atthe same time this diaphragm action acts against the ball, shooting theball out through the barrel 11 in anobvious manner. `The next succeedingball in the magazine drops down by gravity and under the action of theplunger or follower 18, and the air in the shooting drum is replenishedby the suction intake which is developed as the diaphragm is released byremoving hand pressure therefrom.

It is thought that the description taken in connection with the drawingwill enable a clear understanding of the invention to be had. Therefore,a more lengthy description is thought unnecessary. y

While the preferred `embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may 35 be resorted to if desired.

What is claimed is:

1. A gun of the class described comprising a pneumatic device embodyinga receptacle having a flexible diaphragm dening an air trapping andexhausting chamber, a barrel attached to the marginal rim portion ofsaid container, and means for feeding projectiles into said barrelcomprising a container secured to said receptacle in communication 9bwith said barrel and a spring-pressed follower in said container.

2. In a device of the class described, an air trapping and noiseproducing device com- Y prising a pan-like receptacle having aconcavo-convex bottom and a marginal rim, an outstanding peripheralcoupling, a nipple threaded in said coupling, and a closure diaphragm,together With a barrel connected With said coupling and means :torfeeding projectiles into the barrel.

3. Inl a device of the class described, an air trapping and noiseyproducing; devicev comprising a pan-like receptacle having, a con- ,ocavo-convex bottom and a marginal rim, an outstanding peripheralcoupling, a nipple" threaded in said coupling, and a closure diaphragm,together with a barrel connected With said coupling and means-forfeeding l5 projectiles into the barrel, means comprisinga magazine withanupstandi-ng; cylindricalcontainer and a spring pressed follower insaid container.

4i.
